Definitions
- the invention relates to a method and a circuit arrangement for the feedback of the commutation energy in three-phase motor drive systems with a current intermediate circuit converter.
- FIG. 1 Today, in practical applications for current intermediate circuit converters, the so-called phase sequence inverter (K. P. Philips, “Current Source Converter for AC Motor Drives,” IEEE Trans. Ind. Appl., Vol. IA-8, pp. 679-683, November/December 1972) is almost invariably used, FIG. 1 .
- phase sequence inverter In a phase sequence inverter, the commutation capacitors are adapted to the leakage inductance of the motor being used. It is therefore very problematic to use a phase sequence inverter for driving different motors having different leakage inductances.
- the object is achieved by a method, wherein in a first step the created commutation energy is stored in a commutation capacitor. In a second step the commutation energy is directly fed from the commutation capacitor to the current intermediate circuit.
- the commutation energy is temporarily stored, preferably in an intermediate circuit inductor, and in the following commutation in the inverter, this energy swings back into the commutation capacitor (reactive commutation power).
- a circuit arrangement that comprises a commutation capacitor for storing the commutation energy created during an inverter commutation.
- the circuit arrangement further comprises two controllable semiconductors and a diode connected in series in the current intermediate circuit.
- the invention is advantageously applicable in three-phase motor drive systems where energy feedback to the mains and/or a simple, sensorless positioning by means of synchronous motors is desired. Elevator technology is a typical field of application of such drive systems.
- FIG. 1 The classical phase sequence inverter.
- FIG. 2 Exemplary embodiment of a circuit arrangement implementing the invention.
- FIG. 3 Another exemplary embodiment.
- FIG. 4 Explanatory drawings of the exemplary embodiment according to FIG. 2 .
- FIG. 2 shows a typical circuit for implementing the method described in claim 1 .
- RIGBT components, 4 and 5 symbolize a reverse blocking component that is switchable on and off by the gate electrode. According to the state of the art, this component is either
- Current source 1 is formed by a line-commutated rectifier connected to the AC network together with intermediate circuit inductor 12 .
- Positive power source terminal P 1 is connected to positive inverter terminal P 2 , and three-phase motor 11 is connected to the outputs on the motor side of inverter 2 .
- the inverter 2 comprises no commutation capacitors.
- the three motor side outputs of inverter 2 are connected to the three middle connections of diode bridge 10 by respective triac components 7 , 8 , 9 .
- the common cathode of the three upper diodes of diode bridge 10 is connected to the positive terminal of the commutation capacitor 3
- the common anode of the three lower diodes of diode bridge 10 is connected to the negative terminal of the commutation capacitor 3 .
- the positive terminal of the commutation capacitor 3 is connected to the collector of the first RIGBT 4 , its negative terminal is connected to the emitter of the second RIGBT 5 , the emitter of the first RIGBT 4 is connected to the cathode of diode 6 , and the collector of the second RIGBT 5 is connected to the anode of diode 6 ; diode 6 is connected in series with the negative conductor line, the cathode is connected to the negative current source terminal N 1 and the anode is connected to the negative inverter terminal N 2 .
- FIGS. 4 a to 4 e show the different phases of a complete inverter commutation.
- FIG. 4 a shows the conditions prior to the commutation.
- the current is flowing through motor phases a and b.
- the inverter commutation is initiated by the simultaneous switch-on of RIGBT 26 , switch-off of RIGBT 25 , ignition of triac 8 and triac 9 .
- RIGBT 4 and RIGBT 5 are simultaneously switched on.
- the intermediate circuit current is flowing through commutation capacitor 3 and is discharging it.
- the intermediate circuit inductor 12 is taking up the communication energy ( FIG. 4 d ).
- FIG. 3 shows another exemplary embodiment for implementing the method described in claim 1 .
- Thyristor 14 instead of an RIGBT, thyristor 14 is used.
- Thyristor bridge 15 fulfills the function of the three triacs 7 , 8 , 9 and of diode bridge 10 .
